Application filed March 24, 1923.' Y lSerialV No..627,{? 62.

This invention relates to demountable rims. The object lof the invention is the production of arim for the wheel of a vehicle, `which can be easily demounted `from the felly of thewheel. l 4

A second object vof the invention is the productionof a rim which can be collapsed to easily mount a tire thereon, or remove it therefrom. VA third object is the production of'a rim composed of sections hinged to each Y other and also with av pair of sections detachably locked to each other.

The accompanying drawings show exemplifications of the invention in which Fig. l represents a side elevation of the demountvable rim in operative position and a pair of sections thereof in dot-ted lines when in a collapsed position; Fig. 2 shows a section of Fig. l on the kline 2 2 viewed in t-he direction of the arrows A.; Fig. 3 indicates an enlarged section of Fig. 2 on the line 3, 3; Fig. 4 shows an enlarged plan view of fragmentary portions of a pair of sections of the rim; Fig. 5 indicates a section of'Fig. 4`

on the line 5, 5; Fig. 6 shows a bottom View of F ig.'5 withthe fragmentary portions of the sections of the rim located at right angles to their positions represented in Fig. 5, indicating the collapsible feature of the rim; Fig. 7 is a top plan view of Fig. 6;

Fig. 8 represents one of the portions of Fig. before being assembled; Fig. 9 shows a view similar to Fig. 8 with a modification; Fig. l() shows a top plan view of' a locking plate and Fig. ll indicates a section of Fig. l0 on the line ll-ll.

TheA rim in this instance is indicated with4 three arcuately shaped sections designated in their entireties by the letters D, E and F. f

The sections D, F and D, E are hinged in a similar manner to enable them to collapse. The abutting ends of the section D and the sections E and F are on radial planes of the rim. The connectionsvbetween the sections D and Fwill now be described in detail,wvhich will suffice also for the similar connection between the sections D and E. The section F comprises the approximately channel shaped body portion with the inner face V21 adapted to bear on the felly of the wheel on which it is mounted and the outer face 22 which is adapted to support the tire of the rim. An opening 25 is formed in the body portion 2O adjacent to' one end thereof. A narrow projection 26 in the body portion 30,and forms a narrow f projection36 similar to4'26 which extends over Vandv completely across the opening and forms a locking means therewith.

An approximatelyk channel shaped lockingplate for the sections D and F comprises the Y raised central portion 40 with theV locking jaws 41 and 42 extending from vthe ends thereof. vOpenings 43' areformed between the central portion 40and the jaws 41 and 42. The openings 43 are wderenough to engage the projections 26 and 36.

The locking plate is located upon the ini ner faces 21 and3l ofthe sections of theVK Y rim and the jaws 41 and 42 are respectively Vinserted in the openings 25 and 35, before the projections 26 and 36 are bent in position as shown in Fig. 8. The said projections 26 and 36 are then brought down upon the jaws 4l and 42 and their ends enter the openings 43. By this means the `sections D and F and the said .channel shaped'locking plate are permanently hinged together. f

The sections E and F are connected by a latch locking device, which comprises the stationary plate 'fastened to the body-.por-

tion 20 of the section F, and which has formed therewith the depending lug 52 having the inclined indent53 at one end thereof. The lug 52 normally enters and lockswith an opening54 in the body portion 55 of the section E. Upon the body portion 55 of the section E is slidably supported a latch 56 with the tapered end 56a.l YAn elongated opening 57 is formed vin the latch 56. Guide strips 58 are formed with the opening 57.

'A guide pin 59 with thehead 60 extends-k from the body portion 55 of the section E and extends through the opening, 57 with thev r head 60 bearing on the guide strips" 58. When the latch 56 is in its closed position" its tapered end 56.l locks with the indent 53. The abutting edges of the sections E and F are shown at 61.

In'F ig. 9 the construction of the section F is modified by omitting the projection26 and substituting thereforthe plate v which is fastened tothe bodyy portion 2() after thev co i,

hinge plate with its lugs 41 and 42 is placed in position.: l f 'f To disengage the tire, not shown, from the Vrini,.1the said rimis first disengaged from the telly of'thewh'eel in the usual manner.

The sections E and 'F are Vunlocked :trom

Y K l .Various modifications may be made in fthe` construction-of thev rim and its appurtenances andthe present exemplification of Yabutting ends and a locking plate spanning said ends of the sections with its end portions inA the Asaid'opeiiings of the sections,Y
